Reduced Voltage Starters, Class 36 & 37, 88

Class 36 and 37 electromechanical reduced voltage starters

Siemens manufactures the three commonly used electromechanical reduced voltage starters. Each one is designed for specific application requirements and consists of auto transformer, wye-delta and part-winding starters. The reduced voltage starter:

  • Reduces inrush current
  • Provides smoother acceleration of  the load
  • Reduces starting torque
  • Reduces stresses on mechanical linkages

Class 88 NEMA reduced voltage pump control panels

The Siemens Class 88 reduced voltage starter pump controllers consist of the same type of Class 37 starters and their benefits with added features. The added features make the Class 88 ideal for pump control applications and include the following:

  • Type 3/3R enclosure which is fully gasketed to ensure a dust tight and water tight seal
  • Rugged 30 mm H-O-A switch and Start push button as standard
  • The ESP200 solid-state overload relay has a protective coating on the circuit board which gives it superior protection against high humidity, condensation and corrosive environments.
  • UL rated as Service Entrance Equipment
